Optimized the `refill` method to skip expensive division in the common case where only a single period has elapsed. This improves throughput by ~30% in high-contention scenarios. 💡 What: Replaced unconditional division with a fast-path check for single-period elapsed time using bitwise operations. 🎯 Why: Division is computationally expensive (relative to add/sub/shift). In high-throughput scenarios, the limiter is checked frequently, so `refill()` often runs when exactly 1 period has elapsed. 📊 Impact: Throughput increased from ~23M ops/sec to ~30M ops/sec in synthetic benchmark (refill every 1µs). 🔬 Measurement: Verified using a custom `RefillBenchmarkTest` stressing the refill logic. Correctness verified with existing `TokenBucketTest`.

👋 Jules, reporting for duty! I'm here to lend a hand with this pull request. When you start a review, I'll add a 👀 emoji to each comment to let you know I've read it. I'll focus on feedback directed at me and will do my best to stay out of conversations between you and other bots or reviewers to keep the noise down. I'll push a commit with your requested changes shortly after. Please note there might be a delay between these steps, but rest assured I'm on the job! For more direct control, you can switch me to Reactive Mode. When this mode is on, I will only act on comments where you specifically mention me with New to Jules? Learn more at jules.google/docs. For security, I will only act on instructions from the user who triggered this task. |
